MEANS FOR VENTILATING BUILDINGS.

SFEGIFIGATION :Eorm'mg part of Letters Patent No. 697,815, dated April15, 1902.

Application filed October 21, 1.901. Serial No. 79,449. N model.)

To all whom it may concern.-

Be it known that I, THOMAS DARLINGTON, builder, a subject of the King ofGreat Britain, residing at and whose post-office address is 261 and 263Moray street, South Melbourne, in the State of Victoria and Commonwealthof Australia, have invented Improved Means for Ventilating Buildings, ofwhich the following is a specification.

Hitherto provision has been made for ventilating buildings by leavinggaps or openings in the brickwork at intervals and by building in agrating on either side,'those intended for the interior of the roombeing usually of a more or less decorative character. Apart from thecost of this means of ventilation there are other drawbacks, among whichmay be mentioned the fact that the inrush or discharge of air isconcentrated instead of being diffused evenly around the room orbuilding. I have therefore devised the herein-described means forventilating buildings, which while being free from some of the defectsincidental to the means usually employed can be applied in a Variety ofways, according to the nature or the particular part of the building tobe ventilated.

In order that my invention may be readily understood, I will describe itby reference to the accompanying drawings, in.wl1ich Figure l is aperspective view illustrating my improved means for ventilatingbuildings. Fig. 2 is an elevation of a course of brickwork, and Fig. 3is a section of part of a building fitted with my said invention. Figs.4 to 12 are various views illustrating the construction of the differentparts of my improved means for ventilating buildings. Fig. 13 is a frontelevation illustrating the application of a convenient shutter forclosing the ventilating-openings, if desired.

The same letters of reference indicate the same parts in all thefigures.

My invention comprises an oblong block A of brick or other suitablematerial which can be molded, cast, or otherwise manufactured cheaplyand which will be suitable for being built into brick or stone work orsecured within a wooden or other wall of a building. The upper surfaceof this block A is horizontal for the greater part of its width, asillustrated at B, while about onethird of its said upper surface isinclined, as illustrated at O. This inclined surface as constructed isprovided at intervals with bosses or projections D, the upper surfacesof which are flat and comparatively broad. The spaces left between theseprojections are sufficiently wide to insure perfect ventilationwithoutbeing high enough. to allow mice and other small animals to passthrough.

Resting upon the flat surface B of the block A are two bars E of iron orother suitable material, the adjacent surfaces of which are formed withalternate projections F and recessses G. The height of these two bars ispractically equal to the height of the projections D on the block A, sothat when placed tal surface B of the other block, care being taken toset the inclined surface 0 on the inside of the wall in order to keepout the weather.

The bars E can be used in lieu of the hoopiron ties usually employed inbrickwork, or by placing two bars face to face, with their projectionsin engagement with each other, as illustrated in Fig. 12, they willserve as plates for various purposes. They can also be arranged at rightangles to each other to serve as a corner or angle tie, or they can becut off to suitable lengths and be fitted in position for the purpose ofbinding a hollow wall together.

The arrangement illustrated in Fig. 13 can be conveniently employed forclosing the ventilating-openings inside a room, if desired. It consistsof a plate of hoop-iron or similar material suspended by parallel links,to one of which is attached a projecting arm or lever operated by a cordwhich can be pulled down in order to raise said shutter, and thus closethe ventilating-openings, or can be released to allow said shutter tofall, and thereby uncover said openings.

l ,7 .w n. w

It will be evident to builders and others skilled in the art to whichthis invention relates that the improved means for ventilating buildingsherein described can be set in the walls at any convenient positions.For instance, they might be arranged to discharge just above the lowermolding of the cornice, as illustrated in Fig. 3, or they could bearranged to discharge just above any article of furniture in the room.

Having now particularly described and ascertained the nature of my saidinvention and in What manner the same is to be performed, I declare thatWhat I claim is t 1. Improved means for ventilating buildings comprisingblocks (such as A) of brick or other material having part of their uppersurface inclined and fitted with projections (as D) atintervals incombination With rollediron or other bars (as E) having their adjacentsurfaces formed with projections (as F) the whole being constructed andarranged substantially as and for the purposes specified and asillustrated in the accompanying drawings.

2. In means for ventilating buildings, oblong blocks of brick or othermaterial having part of their upper surface inclined and formed withprojections (as D) along one side, substantially as and for the purposesspecified, and as illustrated in the accompanying drawings.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

THOMAS DARLINGTON.-
